Group Video Chat is rolling out to Android and iOS devices and the desktop version of Messenger, worldwide.

You can see up to six people at a time, but up to 50 people can join in and choose just to listen in and join via voice, or be on camera. Once more than six people are on the call, just the dominant speaker is shown to all participants.

To get started, you'll need the latest version of Messenger. All you have to do is jump into an existing group conversation, or create a new one. Then tap on the video icon on the upper right of the screen to enter the video chat, and everyone in the group will be notified. Each person can join when they are ready with just one tap. For an extra nudge, you can also directly ring just a few people or the whole group.
